Product Description
Product Overview
HDPE Column Point Rough Surface Geomembrane is engineered with specialized columnar or point-like surface texture to significantly enhance friction coefficient and adhesion with soil and other materials. This geomembrane provides superior corrosion resistance and impermeability for demanding industrial applications.
Key Features & Benefits
- Enhanced Friction Coefficient: Column point design provides superior stability on slopes and vertical surfaces
- Excellent Impermeability: Effectively prevents water and pollutant penetration
- Chemical Resistance: Withstands erosion from various chemical substances
- Environmental Stress Crack Resistance: Maintains integrity in harsh conditions with ≥300 hours performance
- Temperature Adaptability: Operates effectively across wide temperature ranges from -70°C to high temperatures
- UV Resistance: Maintains ≥50% OIT retention after 1600 hours of ultraviolet exposure
Industrial Applications
- Slope Engineering: Enhanced stability for slope seepage prevention projects
- Landfill Operations: Anti-slip and anti-seepage solutions for landfill slopes
- Tailings Ponds: Seepage prevention and stabilization to contain harmful substances
- Water Conservancy Projects: Enhanced anti-seepage capacity for reservoirs, dams, and water structures
